Portrait photographers demand the attractive bokeh effect that large-diameter lenses offer, as well as outstanding resolution. Fulfilling the exacting standards of the Art line, the Sigma 85mm F1.4 DG HSM | Art delivers both of these elements at the highest level. The bokeh effect is so precise, you can focus on the pupil of the subject’s eye while blurring the eyelashes. Adding to the effect, the area in focus is extremely high-resolution while the bokeh area is very attractive in appearance. The Sigma 85mm F1.4 DG HSM | Art incorporates 14 lens elements in 12 groups, a remarkable structure that helps the lens deliver ultra-high-resolution. This lens is therefore an excellent match for full-frame DSLRs offering 50MP or higher resolution.

Key features

1. A design that prioritises optical performance without compromise.● Outstanding resolving power and minimised chromatic aberrations help make this the ultimate lens for portraits: To create a top-performing 85mm F1.4 lens, Sigma leveraged its latest innovations in design and materials. The result is the ultimate lens for portraits. By taking chromatic aberrations to the absolute minimum, this lens offers performance that goes beyond, including incredibly sharp resolution and a beautiful bokeh effect.● Image quality perfect for ultra-high-megapixel digital cameras: Ultra high-megapixel full-frame DSLRs offering 50MP or higher resolution are now available, and nothing will bring out the performance potential of these cameras better than the fundamental performance of the lens. The Sigma 85mm F1.4 DG HSM | Art incorporates two elements made of SLD (Special Low Dispersion Glass) and one element with a high rate of anomalous partial dispersion and a high index of refraction. These features help ensure a clear image throughout the plane. The optical system also minimises sagittal coma flare for outstanding image quality without streaking, even at wide-open apertures.● Sigma’s fifth large-diameter f/1.4 lens for full-frame sensors: Sigma is the only lens manufacturer thatcovers 20-85mm at f/1.4 brightness in its lineup. This latest lens reflects our experience with this specification and insistence on offering only the best.● The beautiful bokeh effect that only a large-diameter lens can offer: Elements made of SLD (Special Low Dispersion) glass and an optimised power distribution help minimise axial chromatic aberration. In the areas in front of and behind the point of focus, the optical system produces an attractive and natural bokeh effect by producing a smooth gradation of focus and minimising streaking.

2. An all-new lens that leverages SIGMA’s latest design technologies.● Newly designed HSM for nimble AF control: The newly designed Hyper Sonic Motor (HSM) offers 1.3 times the torque of its predecessor. Even at low speeds, it offers exceptionally stable performance, and the updated AF algorithm helps ensure nimble autofocus performance. In addition, full-time manual focus override allows the lens to be switched to manual focus simply by rotating the focus ring, even during continuous AF. The user can quickly find the perfect focus without needing to touch the focus mode switch.
